. PATENT OFFICE SCHWA'RZKOPF, 0F BALTIMORE, MARYLAND DETERGENTDISPENSING DEVICE Application filed May 13,

This invention relates to new and useful improvements in a detergentdispensing device particularly adapted for use with dish washingmachines wherein water in a spray b or other form is fed to the device.

The primaryobject of my invention is to provide a detergent dispensingdevice wherein a constant and uniform quantity of detergent solution isfed to the wash water in direct relation to the amount of water fed tothe dispensing device.

Other purposes, advantages and characteristic features of the inventionas well as the details of construction constituting the preferredembodiment herein disclosed will be more readily understood from thefollowing description taken in connection with the accompanying drawing,in which:

Figure 1 is a top plan view of my invention. 1

Figure 2 is a side elevation of my invention. Figure 3,is a verticalsectional view taken on the line 33 of Figure 1. Figure 4 is a verticalsectional view embodying a modification of my invention.

Referrin ing: The etergent container which is of a substantiallycylindrical form' and is made The cover for the container includes an inverted conical portion 2 having an opening 3 formed in the lower centralportion thereof.- The other edge of the conicalportion forms a verticalwall 4 having a horizontally extending rim member 5 provided with oprnings 6 and 6' formed in diametrically opposite sides of the conicalmember. A flange 7 extendsv from the rim and is adapted to snugly engagethe side wall of the container 1. Particular attention is directed tothe fact that the size of the conical member is dependent on the mannerin which the clear water is furnished, a. larger area being necessarywhen same is provided in spray form rather than a steady stream. Theopening in the conical member is dependent on the character of thedetergent used, that is, the stronger the detergent and more solmoreparticularly to the drawof a non-corrosive material. is designated 1.

through the dispensing device to furnish the necessary detergentsolution. v Th only difference existing in the modification shown is theprovision of the wall 8 which does not in any way materially affect theoperation of the device.- It merely limits and in fact eliminates allair space within the container when the device is in operation.Attention is directed to the fact that the lowermost portion of the coneextends below the rim por-' tion of the cover provided with the outletopenin s 6 and 6'.

Furt er, in the detergent devices previously known the flow of liquidcharged with a detergent continued until the device emptied itself' ofall liquid and in view of this fact that all the detergent in thedispensing device became entirely dissolved shortly after themachinestarted operation all of the detergent would needlessly be exhausted.

In my invention this waste is completely eliminated in that the flow ofliquid charged with the detergent stops simultaneously with the stoppingof the operation of the washing machine.

The flow of fresh water to the dispensing device controls the feed ofthe liquid detergent and it is obvious that irrespective of the numberof times the machine is stoppedand started orthe intervals betweenstopping and starting the strength of the detergent liquid fed would atall'times be substantially uniform.

' In operation, the device is placed in some convenient location withinthe washer to'receive fresh water in spray or other form which iscollected on the inverted conical --member- 2 and-fed within thecontainer 1 through the opening 3 and after thewater has become chargedthrough mixture with the detergent, same'is forced out through theopenings 6 and 6 formed in the rim of the" cover. It is obvious that anynumber of outlets could be formed in the rim portion 5 but it has beenfound from actual practice that two openings work satisfactorily. andthe device gives the best results.

Having thus described my invention, I claim:

1. .A detergent dispenser comprising a cylindrical container, aninverted conical member having an openipjg in the central'portionthereof, a vertical w extending downwardly from the outer edge of saidconical mem= her, a horizontally extending rim projecting outwardly fromthe vertical wall and having openings on diametrically opposite sides ofthe conical member and a flange projecting from the rim to engage theouter side wall of the container.

2. A detergent receptacle including a container, a hollow invertedconical member having an inlet opening, a projection extending from theouter edge of said conical member engaging the outer edge of thecontainer,

forming in conjunction with the conical memher, a cover for thecontainer, said projection having openings formed therein, and the upperouter edge ofthe inverted conical member being at a higher level thanthe outer edge of the projection and also at a higher level than theopenings in said projection.

In testimony whereof I aflix my signature.

J. RAY MARTIN.
